Specification of Letters Patent.

"llatented Nov. 28, 1916.

Application filed January 7, 1916. Serial No. 70,760.

To all whom it may concern Be it known. that I, Ania-{U11 E. CARLINE, a citizen of the United States, residing at Overland, St. Louis county, and State of Missouri, have invented a new and useful Concrete Post, of which the following is a specification.

This invention relates to concrete posts, and has particular reference to devices for connecting stretches of wire to the posts for the formation of fence structures.

An object of the invention is to provide a concrete post equipped with a simple and durable device which may be manufactured cheaply and whereby stretches of wire may be securely fastened to the post, the elements of the fastening device being readily assembled.

Another object of the invention is to provide a fastening device for attaching stretches of wire to a concrete post structure including novel. means for embedding one of the elements in the post body, said fastening device including a socket anchored in the post body, a removable pin adapted to support the wire and to be received within the socket, and a binding device for holding the parts in adjustment and the wire in attachment with the post.

lVith the foregoing objects as well as other advantages and features attainable from the present invention and readily appreciated without specific mention, in view I have produced a suitable embodiment of my invention which is fully disclosed hereinafter, reference being made in the course of the description to the accompanying drawing, in which Figure 1 is a view of a section of a fence employing the invention and illustrating the practical application of the invention. Fig. 2 is a cross section through the post illustrating the manner in which an element of the fastening device is embedded and anchored in the post structure, the parts assembled and the wire held in adjustment. Fig. 3 is an elevation of a section of the post embodying the present invention. Fig. 4: is a vertical section through a section of the post taken on a line such as 44 of Fig. 2. .Fig. 5 is an isometric view of the em bedded element and the removable pin constituting parts of the fastening means.

In the embodiment of the invention illustrated in the drawings, the post structure 1, which may be of concrete or other plastic material, is provided with a series of fastening devices for holding the stretches of wire 2 of a fence structure in spaced position, the fastening devices being arranged at suitable intervals in one facercf the post structure.

The fastening devices include an embedded member comprising a socket 3 provided with eXtensions in the form of angular legs a. This embedded member is positioned in the post body while in the plastic state and so disposed that the face of the socket projects only slightly from the edge of the post and so that the angular extensions of the members 4: engage behind reinforcing rods 5 disposed vertically at the core or center of the post body. When the post body hardens the embedded member is firmly held in position and, since the post body is reinforced, the reinforcements engaging against the lateral projections of the members a, the embedded member is designed to withstand substantial strain without weakening the post body and without danger of becoming loosened therefrom.

As the ends of the socket 3 are substantially flush with the edge of the post, the posts may be handled for shipment or other purposes without danger of damage tothe embedded member of the fastening device. As the remaining elements of the fastening device are interchangeable and removable they may be shipped in bulk separate from the posts and assembled after the posts have been set in position. The additional elements of the fastening device include a removable threaded pin 6 which is provided with a longitudinal slot 7 disposed on one end of the pin to a depth substantially onehalf the length thereof. The pin 6 is threaded throughout its length and is adapted to be screwed into the embedded socket 3 for a sufficient distance to provide an engagement with the socket so that it can not readily be pulled out of the socket, and so that when in position the bottom of the slot 7 will be substantially in the same plane as the face of the socket '3, the extending end of the pin 6 projecting for some distance from the face of the socket.

The stretches of wire are seated in the slot 7 and are bound in position by a binding device 8 in the form of a polygonal headed nut, the binding device 8 being adapted to thread over the extending end of the pin 6 and screwed down to a posi tion so that the inner face will engage against the wire holding the same firmly in place between the edge of the bottom of the slot 7 and the binding device.

It is preferable in assembling the binding device that the pin 6 be seated in the socket 3 so that there will be a slight relative movement, thereby preventing a sharp flexing of the wire at the edge of the pin or shearing action by the sharp edge of the pin. when vertical strain comes upon any of the stretches of the wire. This arrange ment permits the pin 6 to move with the wire.

In referring to concrete posts I do not desire to imply a limitation of the embodiment of the invention, for the reason that it is perfectly apparent that the fastening device may be embedded in any plastic support. I am aware that changes in design may be made Without departing from the spirit and scope of the invention, and I do not desire to limit myself therefore to exact details, except where specifically claimed in the appended claims.

What I claim and desire to secure by Letters Patent is 1. The combination with a concrete post body, of a series of fastening devices each comprising a threaded socket, extensions in the form of angular legs extending from one end of said socket, said socket with said extensions adapted to be embedded in the post body, vertical reinforcements in the post body adapted to engage with said an; gular extensions effectively to anchor said socket in position, a removable pin arranged to be threaded into said socket, and a binding device operable effectively in connection with said pin to clamp the wire in position, substantially as specified.

2. A concrete post comprising a body por tion, a series of fastening devices including for each device a socket having a body portion in which is formed a threaded central opening, extensions from the rear face of said socket portion extending rearwardly and laterally, a pin being of the same di ameter throughout and having threads throughout its entire length on its exterior surface, a slot in said pin extending to a depth so that when the pin is threaded into the socket the base of the slot will be substantially in the same plane as the exterior face of the socket, and a binding device which threads over the end of the pin and is adapted to retain the wire seated in the slot substantially flush with the face of the post, substantially as specified.

3. A concrete post being provided with a series of devices for fastening wire thereto comprising a socket member having a body portion with a central threaded opening, angular extensions from the rear face of said socket portion, a cylindrical pin threaded exteriorly throughout its length and be ing provided with a slot in one end thereof adapted to seat in said socket, so that the base of the slot will be substantially flush with the face of the socket, and a nut adapted to be threaded over the extending end of said pin for holding a stretch of wire seated in said slot, substantially as specified.

In witness whereof, I have signed this specification in the presence of two subscribing witnesses.
